Estrogen Enhances Endothelial Differentiation and Angiogenic Function of Adipose-Derived Stromal Cells to Improve Therapeutic Outcomes in Critical Limb Ischemia.
Article in Cells, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundAging, especially after menopause, reduces the quantity and function of adult stem cells. Estrogen deficiency impairs proliferation, differentiation, and regenerative capacity. This study evaluated whether estrogen enhances endothelial differentiation of adipose-derived stromal cells (ADSCs) and improves therapeutic efficacy in critical limb ischemia (CLI).
methodsMale-derived ADSCs were assessed in vitro for endothelial differentiation using flow cytometry, biochemical assays, and angiogenesis analyses. Therapeutic effects were tested in a rat CLI model using endothelial-differentiated ADSCs (ED-ADSCs) with or without 17β-estradiol (E2). An ovariectomized (OVX) model examined estrogen deficiency and supplementation in vivo.
resultsE2 promoted endothelial differentiation, increasing ERα/ERβ expression and activating PI3K/Akt/eNOS and MAPK signaling. This led to elevated VEGF expression, enhanced tube formation, and increased CD34
conclusionsEstrogen modulates endothelial-associated characteristics and angiogenesis-related responses of ADSCs via ER-associated signaling, and may contribute to improved functional outcomes in ischemic conditions. E2 preconditioning may represent a potential strategy for stem cell-based therapy in estrogen-deficient settings.
